Function Generator Output Amplification.

I want to take function generator as input (45 MHtz max, square and sine both waveforms) and the amplifier should be able to handle it at input and output. plus provide output current till around 1.6 amps . the lower the noise the better. money isnt an issue
I need circuit, or schematic or name of op-amp i can use...i was thinking of using http://www.ti.com/product/opa1664 as starting point...and I dont have alot of days to design it...any help would be much appreciated!!

and if you know any basic amp designing books/pdf/course that would be great too

 

A lot more information is needed.
What input voltage range?
What are the -Peak and +Peak voltages for input and output?
What supplies are available?
What output voltage range? (telling us current alone doesn't give enough info).

You likely will not find a monolythic opamp that can source/sink anything near 1.6A, particularly with that kind of speed, so you'll have to design something that includes some kind of a power amplifier, which won't be trivial at these power levels. Assuming 1.6A is the rms current into a 50ohm load, that's 128W of output power at HF-VHF frequencies. Including harmonics of the squarewave at 45MHz, then the BW of the amp has to extend into the low UHF frequency range. Certainly not a trivial task, and not something you're likely to find in a forum post.

well the input WOULD BE THIS FUNCTION GENERATOR : http://www.finaltest.com.mx/ProductDetails.asp?ProductCode=AWG5004B

2 or 4 Arbitrary Waveform Differential / Single-ended Outputs
Up to 4.5 Vp-p Single-ended and 9 Vp-p at Differential Output into 50 O
0.95 ns Tr/Tf (10 - 90%) at 0.6 Vp-p
+/– 5 ns Range (50 ps Resolution) Inter Channel Skew Control
SFDR: 80 dBc (1 MHz), 64 dBc (10 MHz)
4 or 8 Variable Level Marker Outputs
Up to 3.7 Vp-p Single-ended Output into 50 O
300 ps Tr/Tf (20 - 80%) at 0 to 1 V

p.s i can buy any function generator, no issue

the max output current can be altered to 1 amps if that helps

no limit of supplies either..all lab supplies

I know that AWG very well, I work for Tek.

What is the load that you intend to drive?

 

the load is a micro coil..with inductance in nH....also resistance is extreamly low

 

guys really need your help

 

Over 3 gigahertz of bandwidth? Over 100 watts? and you want it when?

ROFL!

ROFL!

What....how did u reach over 3 Ghz of BW and over 100 Watts?

 

Assuming 1.6A is the rms current into a 50ohm load, that's 128W of output power at HF-VHF frequencies. .

This says, "over 100 watts".

 

and this says, "300 picoseconds rise time".

ok so help me....the current requirement has been dropped to 1 Amp and also if I will be working with 45Mhtz, then wont rise time be a problem? I am just trying to learn here

 

I'll just throw out a guess here...

Wireless power?

....no ...not wireless power

 

@w2aew
@thatoneguy Look all i really need is 1 amps and for the amplifier to work on 45MHtz..nothing else///there are 3 function generators available. I just need a schematic so I can build the amplifier

Function generator :
Agilent 33220A
Hameg HM8150


Also can this amplification be achieved using this piezo amp:
TREK PZD350??

 

Linear Amp

 

nothing that I can build ?? ..a simple amplifier capable of outputting 45 Mhtz at variable 0.5-1 amp current..and a function gen. at input...!??!
